Get to know your computer components

Do you know what components are inside your PC case and what
is their job? No? Then carry on reading as this article may give you a brief
idea of the computer components.

Some of you reading this article may think “What the hell is
that guy talking about, everyone knows that stuff” but I would say “NO” you
wrong as there are people who doesn't So
please do respect that and don’t write any stupid comments, about how basic
this is.

Now let’s get back to our subject, computer components. What
is inside the PC case? First let me list the main components that every
computer system have and later we take a closer look at every each of them.

When we look at our PC all we see is the case as everything
else is hidden inside. All the components that are listed above must be there
as computer wouldn’t run without them. So let’s take a closer look at the
components. What do we have?

Motherboard -is
the central printed circuit board (PCB) that holds all of the computer
components together. Motherboard is alternatively known as the mainboard,
system board, or logic board on Apple computers.

Processor-Central
Processing Unit (CPU) is the portion of a computer containing the logic
circuitry that performs the instructions of a computer’s programs and process
the data that is accessed by the computer.

Cooler-is
used to keep computer components within their safe operating temperature
limits, by removing the waste heat produced by computer components.

RAM-Random
Access Memory is an integrated circuit that allows store data which is in
current use so that they can be quickly reached by the computer’s processor.

Graphics Card-also
known as video card is an extension card inserted to one of the PCI slots on
the motherboard, and it generates output images to computer’s monitor or
display screen.

Hard Drive-(HDD)
is a computer component that is responsible for storing the large amounts of
data on an electromagnetically charge surface or set of surfaces, so it can be
relatively quick accessed when needed.

Optical Drive-actually
Optical Disk Drive (ODD) is a computer component that uses laser light or
electromagnetic waves to retrieve and store data on optical discs such as CD’s,
DVD’s, BD’s which can store much more data than floppy disks.

Power Supply Unit-also
known as PSU this a component that supplies our computer with energy by
converting the mains AC to DC power which has lower voltage.

Case-The
case is not only about how it looks from outside. This is a component that keeps
all the computer components together in closed case. So they
can operate in safe environment without being accidently damaged or cause any
damage to the property in case of failure.

Optional Components

These listed and explained above are the main ones. However
there is many optional ones that can be installed e.g.

Sound Card-also
known as audio card is an extension card that can be connected to the PCI
slots, and it is responsible for input and output the audio signals to and from
a computer under control of computer software.

Network card-is
an extension card inserted to one of the PCI slots on the motherboard, and it
is one kind of network adapter, that support the Ethernet standard for high-
speed network connections via cables. There are also available and more popular
wireless cards. These allows you to connect to the internet without connecting an
ethernet cable.

There is many more additional components that can be installed
in your PC e.g. Card reader, Fan speed controller etc..
